Android might be targeted by hackers and malware far more often than Apple’s iOS platform, but that doesn’t mean devices like the iPhone and iPad are immune to threats. A post on Russian website Habrahabr.ru draws attention to a fairly serious vulnerability that allows nefarious users to remotely crash apps on iOS 6, or even render them unusable. The vulnerability is seemingly due to a bug in Apple’s CoreText font rendering framework, and OS X Mountain Lion is affected as well.
